\VM. KENYON, OF STEUBENVILLE, OHIO, ASSIGNOR TO JOS. P. HAIGH, A. HARTUPEE, AND JNO. MORROV.

MACHINE FOR MAKING NUTS, WASHERS, &c.

Specification forming part of Letters Patent No. 8,427, dated October 14, 1851; Ressued March 18, 1856, No. 361.

To all whom t may concern Be it known that I, VILLIAM KENYON, of Steubenville, Ohio, have invented a new and Improved Machine for Cutting and Perforating Iron Nuts and Washers at One Operation; and I declare the following to be a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon.

F igurel, is a front view of the machine. Fig. 2, is an end view. Fig. 3, is a sectional side view. Fig. 4f, is a full side view. Fig. 5, is an end view showing an end representation of the square punch. Figs. 6 and 7 represent the bracket Q and mandrel P. Fig. 8 is a sectional drawing of the machine.

A, A, is the frame.

B, B, is the cam shaft.

O, O, are the outer cams working in unison with equal stroke.

D, D, are the outer cam yokes.

E, E, is the opening in which plays the round punch L the bracket Q and the mandrel P.

F, F, is the shoving head which is attached to the outer cam yokes by the rods G, Gr, and works in V slides O. O.

G, G, are the rods which connect the shov ing head F, F, with the outer cam yokes.

H, H, is the center cam being a cut off or half stroke cam and having a further throw than the outer cams.

I, I, is the center cam yoke.

J, J, is a square bar of iron attached to the center cam yoke and supported and guided by the two blocks or bearing K, K, and into ,the other end of which is inserted the round punch L.

K, K, is the guide blocks which guide or support the bar J, J.

L is the round punch which makes the hole and cuts the bar out of the center of the nut.

M, M, Fig. 2, represents the die for cutting the nut.

N, N, is the oval boX containing the die M, M, attached to the shoving head F, F.

O, O, are the V slides in which the shoving head works.

P, Figs. 1 and 6, is a cast steel mandrel which works into the die M, the head of which mandrel is seen at P in Fig. l and which mandrel is perforated with a round hole to admit the `round punch L through the die M, into t-he square punch T.

Q, Q, is the arm or bracket the bottom of which works in slides R, R on the floor of the frame A, A, A, and is held close to mandrel P, by a spring. R, R, the dovetail slides in which works at the bottom of the frame the brackets Q, Q.

S, S, is the slat through which the to be cut into nuts passed to the die M.

T, T, is the stationary punch over which the die M, moves and cuts the bar. Its form may of course be round, octagonal, &c.

U, U, is the hole in the center of the square punch through which the bar is forced.

The principle and mode of operation of the machine is as follows: The bar of iron to be cut olf into nuts is shoved through the slat S, at the side of the frame A, A, until it fills or covers the recess of the die M then on turning the shaft B, the outer cams O, O, operating upon the outer cam yokes D, D, force forward the shoving head F, F, toward the square punch T, the square mandrel P, at the same time moving to the surface of the die M, leaves so little space between it and the square punch T, and the mandrel being held from receding by the bracket Q, Q, prevents the bar from tipping while the die presses off the end of the bar; and the shoving head advancing by the turning of the shaft B, B, against the bracket Q, Q, the bracket presses against the mandrel P, and shoves it firmly against the nut in the die M thereby depressing and shaping down its corners and squeezing it compactly into the die and causing it to conform more eX- actly to the cavity of the die. By the time the shoving head is half-way on its stroke and the bar is half in two the heel of the interior cam H, H, urges the round punch forward through the nut returning with a quick motion to prevent its exposure to the heat. The round punch thus penetrating the nut cuts a round burr out of its center forming a circular hole for the screw and urging the burr into the circular hole U, in the center of the square punch T, the shoving Ahead then receding while the bracket Q, Q, remaining station being able to move back no greater distance than it had been moved forward by the advance of the shoving head the mandrel P, is drawn back till it'is stopped by the bracket Q, Q, the die M, is drawn 10W piston, the brackethe cross head and from the nut and the nut being thus relieved the moving die-boX constructed and 0per- 10 falls, or it may be knocked off by a lever or ating substantially as described. other contrivance.

5 What I claim as my invention and desire WILLIAM KENYON to secure by Letters Patent is Witnesses present:

The compressing and discharging the nut ELI H. MCFREELY, or Washer by means of the follower or hol- MATI-IIAS CUMMIN.
